ST 1 Platinum Motor Questions

I actually have 2 of these ST1's. They are the same model and year. One has about 23,000 km on it and the other has only 4,000 km. The LESS used bike has a glitch. The "heat" warning flashes at a lower threshold (temperature) than on the other bike. The motor goes into protective mode and slows down its function to avoid overheating. On cool days over level ground it doesn't occur. I believe this is a new problem but I am not sure because it is rarely hot in Portland. QUESTION 1: Is there a code that I can use to view and change the heat sensor sensitivity in the motor hub? Is the motor hub damaged? I have done a bunch of hard resets on the main computer (also located in the motor hub). The "old" motor is absolutely rock solid after all those kilometers but the hub's bearing is getting a bit loose (bummer... also means an eventual rebuild). QUESTION 2: Has anyone broken open these motors for rebuild jobs? I am interested in possibly doing this since I have 2 motor hubs. BTW. These bikes are so awesome to ride! Had them for 5 years and they keep humming.... bulletproof tanks!
